Description

[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mounting mechanism for mounting a support shaft on a pair of support brackets. As for the shaft, the mounting work can be performed by one person. Then, both ends of one support shaft (for example, a support shaft of an exhibit, a support shaft of a mechanical part such as a pulley) are attached to a pair of left and right support brackets already fixed to a high place of the building. The present invention is particularly effective in the case where the object to be supported is attached to the shaft with the object to be supported attached.

2. Description of the Related Art As a conventional mounting mechanism of this kind, the one shown in FIG. 3 is widely used. An outline of this will be described with reference to FIG. The both ends of the shaft 4 are inserted into the lateral holes 3 of the pair of left and right brackets 1 and 2 already fixed to the relatively high wall surface, and the nut 6 is screwed into the screw portion 5 at the outer end to support both ends of the shaft. 1 and 2 are fixed. This mounting operation is performed as follows. That is, one end of the shaft is inserted into the side hole 3 of one bracket, and then
Insert the other end into the side hole of the other bracket. To remove it, reverse the procedure. If the support bracket is located at a high place and the shaft is relatively long, it is very difficult to perform this work alone. It is practically impossible to mount and remove the shaft as described above in the mounted state. The fact that both ends of one long shaft must pass through the mounting holes of the left and right support brackets is a major reason that makes these operations difficult.

[0003]

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and has been developed in such a manner that an object to be supported is previously attached to a support shaft, and the shaft can be detachably fixed to a support bracket. It is an object of the present invention to provide an attachment mechanism for attaching a support shaft to a pair of support brackets.

Means taken to solve the problem The means taken to solve the problem of the present invention are constituted by the following elements (a) to (f). (A) The shaft mounting hole of the support bracket is a U-shaped shaft hole opened at one end surface of the bracket. (B) A window hole is provided on the side opposite to the opening side of the shaft hole of the support bracket. (C) A shaft insertion hole is provided in the web of the U-shaped stopper fitting. (D) A threaded portion of the outer end of the shaft is fitted into the shaft insertion hole of the stopper retaining web. One flange of the stopper is fitted in the window hole of the support bracket, and the other flange is overlapped on the one end surface of the bracket. Fixed to.

[0005]

[Operation] An object to be supported on the shaft is mounted in advance, and both ends of the shaft are passed through the shaft insertion holes of the retaining bracket web, and nuts are screwed into the threaded portions at both ends of the shaft to form an assembly. Take this to the opening side of the opening shaft hole of the support fracket,
With the stopper fitting outside the support bracket, both ends of the shaft are fitted from the opening side of the opening shaft hole of the support bracket. Thereby, both ends of the shaft are temporarily supported by the left and right support brackets. After that, one flange of the stopper fitting is fitted into the window hole of the support bracket, and the other flange is overlapped with the end face of the bracket on the opening side, and nuts screwed to both ends of the shaft are tightened and removed. Press the stopper to the support bracket and fix it. The retaining bracket is
Since the flange engages the window hole of the support bracket and is further securely tightened against the support bracket by a nut, the shaft inserted into the hole of the retaining bracket is
It is firmly fixed to the support bracket via the retaining bracket. By loosening the nut, releasing the fastening to the retaining bracket, and removing the flange of the retaining bracket from the window hole of the support bracket, the shaft can easily be removed from the shaft hole of the support bracket to the opening side. Therefore, the shaft can be easily removed by loosening the nut, shifting the retaining fitting outward, and then pulling the shaft toward the opening of the shaft hole.

[Embodiment] Next, an embodiment of the present invention will be described with reference to the drawings. A T-shaped, L-shaped or inverted L-shaped support bracket 10, 10 is provided with a shaft hole 11 that is open upward, and a horizontally long rectangular window hole 12 is provided immediately below the shaft hole. The width of the web 14 of the U-shaped retainer 13 is slightly smaller than the width of the window hole 12, and the width of the flange 15 below it is equal to the width of the web 14. Both ends of the shaft 16 are screw portions 17 having a small diameter.
A washer 18 is fitted to the small diameter screw portion. A shaft insertion hole 19 is provided in the web 14 of the stopper 13. An object (exhibit, display product, tape roll, etc.) R to be supported by the shaft is attached to the shaft 16, and a washer 18 is fitted to the small-diameter screw portions 17 at both ends of the shaft.
The both ends of the shaft are inserted into the third shaft insertion hole 19, and the nut 20 is screwed into the screw portion 17. As a result, the supported object R, the shaft 16, the washer 18, the stopper 13 and the nut 20 are assembled to form an assembly. The stopper fittings 13 are moved to the outer end of the screw portion 17 and the shaft is dropped into the shaft hole 11 of the support fracket 10 from above. At this time, the washers 18 are located inside the support bracket 10. The lower flange 15 of the retainer web 14 is fitted into the window hole 12 of the support bracket 10 and the upper flange is overlapped on the upper end surface of the bracket. Fix to 10. Flange 15 is window hole 1
2, the retaining fitting 13 is connected to the nut 20.
It will never come off the support bracket unless you loosen it. Therefore, both ends of the shaft 16 are fixed to the support bracket via the retaining fittings. By loosening the nut 20 and displacing the retainer 13 outward to remove the lower flange 15 from the window hole 12, both ends of the shaft 16 can be removed upward from the shaft hole 11 of the support bracket 10.
Note that the opening side of the opening shaft hole 11 of the support bracket 10 does not need to be only upward, and it is sufficient that the shaft hole of the support bracket can temporarily support both ends of the shaft. The reason why the washer 18 is provided is that the support bracket 10 is sandwiched between the washer and the retaining bracket to increase the fixing strength of the retaining bracket to the support bracket. No washer is required when the step between the small-diameter screw portion at both ends of the shaft and the middle large-diameter portion is brought into contact with the inner surface of the support bracket with a sufficient contact surface. Even when the shaft supports a rotating body such as a pulley, the shaft is usually a fixed shaft, so the mounting mechanism as in the above embodiment may be used. However, the shaft can be freely rotated by the support bracket in some circumstances. When it is desired to support the shaft, both ends of the shaft may be rotatably supported by the stopper fittings via bearings. Further, a notch 21 is provided on both sides of the opening side edge of the opening shaft hole of the support bracket, as shown in FIG. 2, for engaging the flange 15 of the retaining metal fitting, and the flange is locked in this notch. Good.

[Effect] The above-mentioned problem of the present invention has not been solved yet and is a new problem. Therefore, it is the most specific effect of the present invention to solve this problem and eliminate the above-mentioned problems inherent in the prior art. Therefore, the present invention itself has sufficient technical inventive step by solving the problem of the present invention. Furthermore, since the operation of attaching or detaching a relatively long shaft to or from the pair of support brackets can be performed easily and easily by one person, the cost of the attaching operation can be greatly reduced, and the operation can be performed more safely. be able to.
